What is the difference between AIS and Form 26AS?

“AIS is an extension of Form 26AS. Form 26AS displays the details of purchase of property, high value investments and TDS/TCS transactions during the financial year. AIS additionally includes savings account interest, dividend, rent received, purchase and sale transactions of securities/immovable properties, foreign remittances, interest on deposits, GST turnover etc. AIS also provides an option to the taxpayer to respond to the reported transactions. In addition, the aggregation of transactions at the information source level is also reported in the TIS.”
